Hello,

 

i compiled vlan module from 2007R1.1 (tarball  and brunch version) but they crash when i plug the vlan cable.

 

NULL pointer access (probably)

Do you have any suggestion?

 

Thanks in advance,

Emanuele:

 

I don't think anyone tested vlan in 2007 - but I'm pretty sure it works on 2008R1.5, and sure it works on trunk (soon to be 2009R1).

 

Any possibility of trying those?
